Matt and Dave's 891 election bus is back!

The 12 seater departed Collinswood at 6am express to the city and the Garden of Unearthly Delights, followed by a stop in Victoria Square, then onto Brighton Beach.

Along the way, politicians will board the bus various intervals to discuss their plans for the State's future.

South Road express

Adelaide

First pick up on the way to Brighton jetty, along South Road, included candidates for the seats of Adelaide, Elder and Bright.

Rachel Sanderson last state election won the seat of Adelaide from Labor's Jane Lomax-Smith and told Matt and Dave she backs Stephen Marshall's plan to expand Adelaide High School.

"When the West Terrace option was put to me I thought what a great idea... when I door knock, people ask how do they get access to Adelaide High, none of them have asked for just a random school anywhere"

Ms Sanderson says she has ambitions to hold a position in the ministry.

"For now I'm just focussing on winning the next election, but should I win certainly a ministerial position would be in my sights in a few years, maybe the next term... however long it takes," she says.

Adelaide Labor candidate David O'Loughlin says the Liberal Party plan for Adelaide High is not in the interests of the electorate.

"I don't believe anybody wants to send their kids [to a school] that's 2500 students with 20 year eight classes that spans across South Australia's busiest road... and built next to a service station.

"We're proposing a school on a third of the Royal Adelaide site right next to the Botanic Gardens and Adelaide Zoo around the corner of the Art Gallery and that sounds to me like a much more desirable location," he says.

Elder

Two candidates for Elder: Annabel Digance (Labor) and Carolyn Habib (Liberal), both took seats on the the election bus.

Ms Digance is campaigning for the state election after previously failing at federal level in 2013.

"One of the big issues for Elder is that we've already experienced the Liberal cuts... through the ripping out of funding through the Tonsley line and I've been campaigning everyday to get that line up and running.

"I also hear about health care and in particular I hear about funding that was ripped out of the neo-natal unit Flinders Medical Centre," she says.

Ms Habib says the Liberal Party will commit to funding neo-natal care.

"I know there has been some really upsetting letters gone out claiming that the liberals don't care which is in fact a complete lie, we've committed 17.5 million dollars to the neo-natal upgrade.

"I think it's really important we stay focussed on state issues, the things that are within our control," she says.

Bright

The final candidate pair to board the election bus on the South Road express was Brighton MP Chloe Fox (Labor) and candidate David Speirs (Liberal).

Ms Fox says she is hoping to win the seat despite her mother Mem Fox, declaring she would pop champagne if she lost.

"Happy if I lose? No, what a foolish question, I'd like to do my job, I really like my job... it's fantastic," she says.

Candidate Mr Speirs says she will consult widely as the member for Bright.

"I think I bring a grassroots approach to this candidacy and if I'm elected I'll certainly be focussing in the suburbs, continue to doorknock... and work out what makes this community tick," he says.
